A balloon catheter assembly to provide blood in inflatable condition

Abstract

A balloon catheter assembly is disclosed. A balloon catheter assembly comprising a proximal part, a middle part, an inflatable balloon and a long tip located at proximal end. The distal end comprising a port for inflation and middle part is connecting member extended from the proximal part end to distal part end. The middle part comprises of three lumens which is extended up to long tip (1) the inner most lumen permit use of a guidewire, (2) a middle lumen is for inflation and deflation of inflatable balloon through proximal part and (3) an outer lumen is comprises of plurality of holes. The plurality of holes of outer lumen spacedly located before and after of the inflatable balloon. The outer lumen hole of is expandable upon starching outer lumen allow to pass blood continuously.

1 . A balloon catheter assembly, comprising:
 a proximal part, a middle part, an inflatable balloon and a long tip located at proximal end;   wherein the distal end comprising a port for inflation;   wherein the middle part is connecting member extended from the proximal part end to distal part end;   wherein the middle part comprises of three lumens extended up to long tip, the inner most lumen permit use of a guidewire, a middle lumen is for inflation and deflation of inflatable balloon through proximal part and an outer lumen is comprises of plurality of holes;   wherein plurality of holes of outer lumen spacedly located before and after of the inflatable balloon; and   wherein outer lumen hole of is expandable upon starching outer lumen allow to pass blood continuously.   
     
     
         2 . The balloon catheter assembly as claimed in  claim 1  wherein the outer lumen is elastic tube. 
     
     
         3 . The balloon catheter assembly as claimed in  claim 2  wherein the plurality of outer lumen holes are located at least 30 mm before and 10 mm after inflatable balloon. 
     
     
         4 . The balloon catheter assembly as claimed in  claim 1  wherein middle tube is stainless steel shaft. 
     
     
         5 . The balloon catheter assembly as claimed in  claim 1  wherein the inflatable balloon is at least dilatation balloon catheter and drug coated balloon catheter. 
     
     
         6 . The balloon catheter assembly as claimed in  claim 1  wherein outer member of middle part and inflatable balloon is made of silicone, latex, polyisoprene rubber, polyethylene, polyolefin copolymer polyethylene terphathalate, nylon and polyurethanes. 
     
     
         7 . The balloon catheter assembly as claimed in  claim 1  wherein an angioplasty stent is crimped on the inflatable balloon.
